Winter Tyres Cost-Benefit Calculator
Work out the yearly cost of running a second set of winter tyres, using your own prices, and see who is more likely to find them worthwhile.
How does the winter tyres cost calculator work?
Running a second set of winter tyres has three main yearly costs: the price of the set spread over the winters it lasts, the fitting cost for two changeovers a year (on in autumn, off in spring), and storage for the set that is off the car. This calculator adds those up from your own figures.
It also has an optional offset. The RAC points out that your summer tyres should last longer when they are not on the car through winter, so the true extra cost is a little lower than the gross figure. How much lower depends on your tyres and mileage, so the offset is left at £0 unless you enter your own estimate.
3 worked examples
All the prices in these examples are my own illustrative placeholders, not quotes or surveyed averages.
Example 1 — Mid-range set, stored at home
A £400 set lasting 4 winters, £15 a tyre to fit, stored at home for free.
£400 ÷ 4 = £100 a year
Fitting (2 changeovers, 4 tyres each):£15 × 4 × 2 = £120 a year
Total:£220 a year
Example 2 — Cheaper set, paid storage
A £300 set lasting 5 winters, £10 a tyre to fit, and £30 a year to store (the RAC mentions some tyre centres charging £7.50 or more per tyre per season, which would be £30 for four).
£300 ÷ 5 = £60 a year
Fitting:£10 × 4 × 2 = £80 a year
Storage:£30 a year
Total:£170 a year
Example 3 — Example 1 with a summer-wear offset
Same as Example 1, but you estimate that keeping your summer set off the car in winter saves about £40 a year of wear. That £40 is an assumption for this illustration, not a measured figure.
£220 a year (as Example 1)
Less summer-tyre wear saved:− £40 a year
Net extra cost:£180 a year
Fitting is a large part of the cost in these examples. Some drivers buy a second set of wheels so they can swap without paying a fitting fee; if so, enter £0 for fitting and include the cost of the wheels in the set price.
Are winter tyres legally required in the UK?
No. The RAC says winter tyres aren't mandatory in the UK, and the AA says the same. Some other countries do require them in winter, so check the rules before driving abroad. Here it is a personal cost-and-risk decision rather than a compliance question.
The 7°C guideline
Winter tyres use rubber designed to stay flexible in cold temperatures. The AA says this applies below 7°C, and the RAC says winter tyres work best below 7°C. The AA adds that they give better braking and handling on snow and ice, and also on wet roads in cold conditions.
7°C is a commonly quoted guide, not a legal or sharply defined threshold. I haven't quoted any grip or braking improvement as a figure, because results depend on the tyres and the tests.
Who may benefit most
This is my own reasoning, not a published rule. Winter tyres are more likely to be worthwhile if:
- you drive on rural, hilly or poorly gritted roads in winter;
- you often drive early in the morning or late in the evening, when it is coldest;
- you park outside rather than in a garage;
- you cover high mileage in winter, or can't avoid driving in snow or ice.
They are likely to matter less if you drive little, mostly in town on well-gritted roads, and can stay home in the worst weather. Only you can weigh the cost against the benefit for your own situation.
All-season tyres as a middle ground
The AA describes all-season tyres as a compromise that avoids swapping tyres twice a year, with a tread somewhere between a normal summer tyre and an out-and-out winter tyre. The RAC says they offer a compromise between winter and summer performance, and that winter tyres carry the M+S and three-peak mountain snowflake (3PMSF) sidewall symbols. Check the sidewall marking and the maker's information on any tyre you are considering.
An all-season set has no second set to buy, store or swap, so it avoids most of the extra cost this calculator measures. It does not claim to match a dedicated winter tyre in severe conditions.
What this calculator can't tell you
Whether it's worth it for you
That depends on your roads, mileage, budget and how much risk you are comfortable with. A calculator can't resolve it into a single answer.
The safety benefit in pounds
I deliberately don't put a £ value on reduced accident or breakdown risk, because it would need assumptions about your conditions that I can't know.
Real prices
Set prices, fitting fees and storage charges vary by tyre size, retailer and area, so the defaults here are placeholders. Get quotes before relying on the result.
Insurance and resale
The RAC says fitting winter tyres should not affect your car insurance but suggests checking with your provider. Any effect on resale value is not included.
Common mistakes
Budgeting for only one fitting
The tyres have to be swapped twice a year unless you keep two sets of wheels.
Thinking winter tyres are only for snow
The AA says they also give better braking and handling on wet roads in cold conditions.
Not checking the stored set
A stored set still has to meet the legal minimum tread depth when it goes back on the car. Use our Tyre Tread Depth Checker before refitting.
Ignoring the summer-tyre saving
Leaving it out overstates the extra cost slightly, as the RAC says summer tyres last longer when winter tyres are used.
Getting the most from a winter set
- Fit them before the cold arrives, because tyre shops can get busy once temperatures drop
- Store the off-season set carefully, clean, dry and out of direct sunlight, so it lasts longer
- Fit a full set of four. The AA says that if you switch, you need four winter tyres
- Check tread depth on both sets, not only the set that is fitted
- Compare with all-season tyres if you want some of the benefit without swapping
🛞 Check your current tread depth
Whichever tyres you run, make sure they meet the UK legal minimum.
Use the Tyre Tread Depth Checker →How we calculate
Gross annual cost = (set cost ÷ winters it lasts) + (fitting cost per tyre × 4 tyres × 2 changeovers) + storage per year.
Net extra cost = gross annual cost − summer-tyre wear saved (the optional figure you enter, £0 by default).
All inputs come from you. The calculator assumes two changeovers a year and four tyres per set, and it does not value any safety benefit.
Frequently asked questions
Are winter tyres a legal requirement in the UK?
No. The RAC and the AA both say winter tyres aren't compulsory in the UK. It is a personal decision based on your driving conditions.
How much do winter tyres cost per year?
It depends on your tyres, fitting and storage. Using placeholder prices, the worked examples above come to roughly £170–£220 a year before any summer-tyre saving. Enter your own quotes in the calculator for a real figure.
Do winter tyres only help in snow?
No. The AA says they give better braking and handling on snow and ice and also on wet roads in cold conditions, and the RAC says they work best below 7°C.
Are all-season tyres a good alternative to winter tyres?
They can be if you want to avoid swapping tyres. The AA and RAC both describe them as a compromise between summer and winter performance, so they don't match a dedicated winter tyre in severe conditions.
Should I fit winter tyres on just two wheels?
The AA says that if you switch to winter tyres you need four. Fitting a full set is the usual advice.
